Spec Builder
Write a precise spec one decision at a time, then see how specificity decides what the AI builds.
Spec Builder
The AI builds whatever you specify — and guesses whatever you leave out. Write the spec for a flashcard app one decision at a time, then send it and see what comes back.
Your spec so far
Pick an option above to start writing the spec…
Specificity: 0 / 10
Make a choice in all 5 sections to send the spec.
How does it actually work?
An AI model fills every gap in your request with a best guess. That makes a specification — a clear statement of what to build, for whom, with which features, under what constraints, in what form — the most powerful tool you have.
Architecting a project is mostly the act of converting fuzzy intentions into precise decisions before any code is generated. The clearer the spec, the less the AI has to guess — and the closer the first build lands to what you imagined.
